with the ST-rr ext. chassis, the truck will be much more stable in the rough sections, and has a lower center of gravity for improved handling, you will however need the longer rear tubular chassis brace, and the longer rear center universal joint, I strongly recommend holding off for the ext. chassis. If you buy the entire ext chassis kit, you get the brace, universal, and the HC knuckles, long wing stay and wheel nuts and main chassis plate all together..........dialed, and its on sale @ Amain right now

thats cheap for a new/unused STR chassis, but the question is, do you want a standard length vs. the new ext chassis thats been released?

Hi dude,
I was actually looking for the buggy chassis. Was initially wondering if this STR chassis would fit the SP2. Anyhow some guys have already told me the STR chassis is longer. So it's a no-go for me

Before you put the cap on, just press on the bladder to see that it is flexible. Some folks build the shocks with too much pressure behind the bladder. Make sure they are all pliable, and then build the shocks. You want to try and get them all the same. When bleeding the BB shocks, you need to unscrew the cap more than with the small shocks, and push the shaft in 3/4 of the way. Make sure all the air and oil has seeped out, then tighten, HARD.
